Wheel Offset Calculators

[Diego74]

ok im very new to vws and I have a 1303 74 so to my understanding to this is if i want to go with 17 by 7 wheels the et should be 55 for all 4 wheels with the use of a 3/8 spacer on the rear. I want to stay stock fenders all the way around and dont want to come to clearance issues. i also understand the rotors need to be drilled to fit the bolt pattern. any info on this would be a big help.
